in the last 15 games (which is basically since he began having regular starts this season) he's scored 8 goals and got 3 assists - that's more than a run but proof of a consistenly quality player - and while I dont know what his defenseive game is like, as a forward his job is mainly to score and get assists - not all teams are like Arsenal where Arteta expects everyone to track back etc
oh and on the Labour point, the conferences prove nothing as they aren't representative as it's people who can afford to take the time off and pay to go plus lots of industry lobbyists
which of course is far less evidence-based than thinking they know Arteta's mind from a heavily edited documentary...
